Abstract
There is provided an apparatus for cutting plant material, in particular tobacco, having a funnel-shaped press in which the charged material to be cut is compressed and fed to a mouthpiece arranged at the outlet end of the press, a knife carrier rotating about a horizontal axis in front of the mouthpiece and having circulating knives which move past the mouthpiece so as to perform a cutting action, a knife grinding device disposed in the circulation path of the knives, and counter knives disposed on the mouthpiece at the outlet end of the press projecting into the circulating path of the circulating knives. The knives are thereby sharpened on two edges by the knife grinding device and the counter knives.
Claims17
In an apparatus for cutting plant material of the type having a funnel-shaped press having an outlet end in which the charged material to be cut is compressed, a mouthpiece arranged at the outlet end of the press to which the compressed material is fed, a rotatable knife carrier disposed in front of the mouthpiece and having a plurality of circulating knives having cutting edges which may be moved past the mouthpiece so as to perform a cutting action, and a knife-grinding device disposed in the circulation path of the knives having a grinding wheel disposed for operative passing engagement with an oblique knife surface of a knife face of the cutting edge of each knife which, when emerging from the mouthpiece, faces away from the material to be cut, the improvement comprising:
- a plurality of elastically resilient counter knives disposed on said mouthpiece which project into the circulation path of the cutting edges of said knives, said counter knives being disposed on said mouthpiece to contact to sharpen an oblique knife surface of a knife face of the cutting edge of each knife facing the material to be cut.
An apparatus for cutting plant material of the type having a funnel-shaped press having an outlet end in which the charged material to be cut is compressed, a mouthpiece arranged at the outlet end of the press to which the compressed material is fed, a rotatable knife carrier disposed in front of the mouthpiece and having a plurality of circulating knives having cutting edges which may be moved past the mouthpiece so as to perform a cutting action, and a knife-grinding device disposed in the circulation path of the knives having a grinding wheel disposed for operative passing engagement with an oblique knife surface of a knife face of the cutting edge of each knife which, when emerging from the mouthpiece, faces away from the material to be cut, the improvement comprising:
- said mouthpiece having at least two relatively free upper and lower edges, at least one of which projects at least partially into the circulation path of said cutting edges of said knives and is formed by a free front face of a strip placed in front of the upper edge of said mouthpiece so as to contact to sharpen an oblique knife surface of a knife face of the cutting edge of each knife facing the material to be cut.
